The material expelled in the supernova can join other clouds and form new stars and thus the cycle is complete.

Note, not all stars follow the above cycle. Smaller stars such as our Sun, would stop fusing elements after they have run out of helium and simply 'puff' off its outer layers. The remaining core becomes a white dwarf which slowly fades over billions of years.

This image sums up the life cycle of stars.
